Veteran broadcaster Larry King says he battled lung cancer this summer but appears to be on the mend. The 83-year-old told US Weekly that a spot on his long was found during a routine checkup and he had surgery in July. The tumor was malignant, but doctors were optimistic since it was found so early. This isn't King's first health scare. The former CNN host has a heart attack in the 1980s and also battled prostate cancer.
